transaction: support cache file in backupentries
We do not want to abort if anything wrong happen while handling a cache file.
Cache file have way to be invalidated and if old/bad version stay no
misbehavior will happen. Proper value will eventually be computed and the wrong
will be righten.
This changeset use the transaction reporter (usually writing on stderr) to write
details about failed cache handling. This will only apply to write operation
using a transaction. The usual update during read only operation will stay a
debug message.
I was on the way to bring these message back to debug level when I realised it
could be a feature. People with write access to the repository are likely to
have the power to fix error related to cache (and it is valuable to fix them).
So let the things as is for now.
